Aggie, a Dexter cow, died at age 18 of old age. Dexter cows live an average of 15 to 20 years, according to zoo officials.

Aggie was born in May 1993. For the past 18 years, she lived in the Barnyard at Prospect Park Zoo next to alpacas, sheep and miniature horses.

“You are beautiful and I would never want to eat you,” wrote one young fan. Another wrote, “Dearest Agatha you are the color to my rainbow…”

“Aggie will be greatly missed,” said Denise McClean, zoo director. “People grew up visiting her and came back to the zoo to see her through the years. She had a big personality and loved the attention.”
